Every week, a new STACK Challenge gives you an opportunity to test your athletic ability and win a STACK T-shirt. Take the challenge and enter to win by tweeting your results with #STACKChallenge.

Get stronger, build power and challenge your entire body in less than five minutes with this week's STACK Challenge, courtesy of trainer Todd Durkin.

To complete the Full-Body Burner Challenge, perform 10 reps of Dumbbell Squats and Shoulder Presses, then 20 Skater Plyos. Repeat the circuit twice more. Time yourself and make sure you're performing full reps with proper form.

Dumbbell Squat and Shoulder Press

Holding dumbbells in an athletic stance, lower into a Squat until your thighs are parallel to the ground

Keep your back straight and your knees behind your toes

Extend your hips and knees to drive out of the squat position and press the dumbbells overhead

Lower the dumbbells to your shoulders and repeat

Use 25-pound dumbbells if possible

Skater Plyos

Bound at least three feet to the left off your right leg

Land on your left foot, bringing your right foot behind and your right hand across your body

Immediately repeat to the other side

The Challenge

Perform three sets of Dumbbell Squats and Shoulder Presses (10 reps) and Skater Plyos (20 reps) as quickly as possible.

How Do You STACK Up?

No Rookie, Pro and All-Star levels this week. Just focus on full reps performed as quickly as possible. Repeat the challenge once a week for four weeks, and strive to beat your previous time each week.
